To all whom it may concern; 1

Be it known that I, PHILLIP J. DELL, Jr., a citizen of the UnitedStates, residing at Waycross, in the county of Ware and State of"Georgia, have invented certain new and useful improvements inSwitcl1-Point Tie- Bars; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The object of this invention is the provision of a novel type ofsectional tie or connecting bar for the points of a railway switch,which can be adjusted in a convenient manner to effect the proper gageof the switch points; also the provision of novel retaining means foreffectively holding the sections in adjusted position.

@ther objects will appear and be better understood from that embodimentof my invention of which the following is a speciiication, referencebeing had to the accompanying drawing forming a part thereof, in which:

Figure 1 is a side view of the connecting bar, showing the sameassociated with the switch points.

Fig. 2 is a detail perspective view of a switch point operating bar,showing the manner of connecting the tie bar sections thereto.

Fig. 3 is a fragmentary top plan view of a railway switch, showing thetie connecting bar connected to the switch points of the switch,

lf ig. d is a perspective view of one of the sections of the tieconnecting bar,

Fig. 5 is a sectional view, taken on the line 55 of Fig. 1.

Referring to the drawing in detail, the letter A designates the mainrails of a track, and B the movable switch points. The switch pointoperating bar 1 extends below the rail A, and is provided at a pointinter mediate its ends and between the rails A "with a U-shaped bracket2, and is also pro vided at points spaced. from the opposite sides ofthe U-shaped bracket 2 with aper" turcd lugs 3, which are carried bycircular plates 1 which rest on the upper surface of the operating bar 1and have threaded stems 5 depending therefrom and received by openingsin the operating bar 1, as shown more particularly in Fig. 5 of thedrawing, the said stein having the lower end thereof provided with a nut6, which is adjustable 1 against the under face of the bar 1, and a jamnut 7 is turned on the lower end of the stem and adjustable against thelower face of the nut 6, for preventing the retrograde rotation of thenut 6. The connecting or tie bar for the switch point is shown asconsist ing of a pair of sections 8, which extend through the aperturedlugs 3 and through openings in the sides of the U-shaped bracket 2, theinner ends of the sections 8 being arrangedin spaced and opposedrelation between the sides of the U-shaped bracket 2. The outer ends ofthe sections 8 are terminally bent upwardly, as shown at 9, andconnected to the plates 10, which are adapted to be secured to the innerfaces of the switch point B by means of fastening elements, which extendthrough the switch points and through apertures in the plates 10. Theinner ends of the sections 8 are threaded, and nuts 11 and 12 areadjustably mounted on the threaded ends of the sections 8, and arelocated on opposite faces of the sides of the U-shaped bracket 2, asshown in Fig. 1 of the drawing. l Vhen it is desired. to adjust theswitch point, the nuts 11 and 12 are rotated so as to cause them totravel away from the sides of the U-shaped bracket 2. The sections 8 arethen moved in the proper direction to effect the proper gage of theswitch points, after which the nuts 11 and 12 are adjusted against thesides of the U shaped bracket 2 so as to hold the rods 8 in adjustedposition. The rods 8 have those portions which extend through theapertured lugs 3 provided with depressions 13, and adjustable throughthe lugs 3 are set screws 14, which are adapted to have their inner endsinterchangeably received by the depressions 13 so as to further assistin holding the sections 8 against movement when in adjusted position.The lugs 3 form supports to the rods 8 at points intermediate theirends, and which will hold the rods against accidental movement if thenuts 11 and 12 become loose. Jam nuts 15 are mounted on the set screws14: and are adj estable against the lugs 3 and serve to preventaccidental retrograde rotation of the set screws 14.

It is evident that various changes mightbe resorted to in theconstruction, form and arrangement of the several parts withoutdeparting from the spirit and scope of my invention; hence I do not wishto limit myself strictly to the structure herein described'and throughthe lugs and adapted to be interclaimed. changeably received by thedepressions in Having thus described my lnvention what the sections ofthe tie bar for holding the I claim as new, 1s: sectlons againstmovement.
